To all w kom t may concern: Y p

Be it known that I, Pi-Iinirrn DE CLAluncY, a citizen of the United States, and a resident of `New York, county and State of New York, have invented certain new and use- `ful Improvements in Folding Typewriting Machines, ofwhich the following isa full, clear, and exact description.

In' the drawings, Figure 1 1s a plan view of the machine 1 Fig. 2 a vertical sectional view thereof,

Fig. 3 a vertical f sectional view of the platen carriageV bed;

Fig. 4 a plany view thereof; Fig. l5A a plan View of a portion of the platen carriage bed', with the platen carj riage moved to its folding position,

Fig. 7 a detail view showing the platen carriage placed von end and thek carriage bed folded; and

Fig. 8 a detail horizontal sectional view of the central carriage bed supporting post,

-platen carriage may be placed vertically on end and the sections of the carriage bed folded upwardly to partly inclose the platen carriage.

There are other important objects and ad vantages of the invention which will appear more fully hereinafter.

. Referring to the various parts by` numerals, 1 designates the base plate of the machine, 2 the bearing for the key. levers, said bearing being in form of a wlre segmental in plan view; `and 3 the'key levers pivoted on said bearing. 4 designates the carriage bed which is formed 1n three.V sec* tions, a central section 5, and two end sections 6 and 7, these latter sections being hinged to the ends of the central section and adapted to fold upwardly and inwardly. The bed is provided with tracks 8, in which is adapted to slide a supplemental bed plate s 9. In this supplemental bed plate the car' f riage is adapted to slide transversely of the f Application led March 29, 1917. Serial No. 158,284.

'machine The supplemental bed is detachably secured in position bykmeans of set plate having a longitudinal flange 12 fitting i the corresponding groove in the central part I of the bed, as shown clearly in Figs. 2 and 4. The upper surface of the plate 11 is flush with the upper surface of the central portion 5 ofthe carriage bed. This central plate 11 1s grooved to receive the supplemental carriage bed 9; and is also formed with tracks 8a, which correspond with the tracks 8 of the section 6. The section 7 of the main carriage bed is provided with tracks 8, as cle'arlykshown in Fig. 4, andare for a purpose which will hereinafter appear. The supplemental carriage bed 9 is formed with longitudinal extending ribs 9b adapted t0- engage the tracks v8 and 8a. This supplemental bed entends from end to end of the' main bed and holds. the tracks of the rotatable plate 11 in alinement with the tracks 8, as clearly Aillustrated in Fig. 4 of the drawins, and locks said plate against rotation. n the upper surfaceof the rotatable plate 11 are fo-rmed two hooks 13, said hooks being formed close to the section 7 of thek main bed and facing towardr the section 6, said hooks being adapted to receive ,the outwardly extending lugs 11a on the end of the supplemental bed. The lugs 11 are raised above the tracks 8 and are adapted to move over said tracksas the supplemental bed is moved toward the right to bring the lugs 11 into engagement with the hooks 13, as shown clearly in Fig. 5.

The supplemental bed 9 is formed along its longitudinal edges with inwardly eXtend ing tracks 14. Sliding on the supplemental bed is the platen carriage 15, the base plate i 16 of said carriagebeing providedA along its longitudinal edges with ribs `17 adapted to lit-in the tracks 14. The platen 18 is supportedV in standards 19 carried by the base` plate 16. .It will, of course, be understood that the base Vplate and the` means for-supporting the platen may be of any suitable construction; and that the platen is to be provided with the usual paper guide 19a,

feed roll 20, and theusual disks or knobs drum 22 is mounted in the supplemental bed,

and the driving cord 23 is connected to the platen carriage, as indicated in dotted lines` in Fig. 4. This driving drum and the connecting cord may be of any suitable construction, and may be arranged as' desired to secure the longitudinal advancement of the carriagev for letter spacing.

When the supplemental carriage bed is in the position shown in Fig. 3, it is rigidly held by means of the set screws 1 0.` The platen carriage is then free to reciprocate upon said supplemental bed. desired to fold the machine theV screws 1.0 are loosened, and the supplemental bed vis moved to the right to bring the lugs 11 into engagement with the hooksd. The ribs 9b of the supplemental bed will then be free of the tracks 8a on the central plate ll, and the supplemental bed with the platen. carriage thereon may be swung upwardly and placed on end substantially in the center of the plate 1l, as shown in Fig. 7. The plate 1l may then be rotated on the central section 5 of the carriage bed, if desired, to bring the paper guide at the back or rear of the machine. The two end sections ofthe carriage bed may then be folded upwardly toward the platen, as indicated in Fig, 7, thereby reducing the width of the machine.

The key levers are provided with an ejitension or supplemental member 3a, said members being pivoted at their forward ends on the pivotwire 2; and the members Sand 8a are connectedtogether by a knuckle Joint 24, whereby upon the depression of the key lever, the supplemental or extension member 3 will be moved upwardly. The type bars 25 are pivoted at 26, and are formed with forwardly extending arms 27. Theparm 27 of each type bar is provided with a pin 28 which enters a horizontal slot 29 in the member 8 of a key lever. 1t is manifest that upon the depression of one of the keys its connected type bar will be thrown .forwardly and downwardly to the platen. The member 3a of each key lever is maintained in its lower or normal position by means of a spring 30, said spring serving to throw the keys and type bars to their normal positions.

rlhe main portions of the key levers are adapted to be swung upwardly and rearwardly to their folded position, as indicated by dotted lines in Fig. 2, thereby very materially reducing the length of the machine. Any suitable means may be employed to support the type bars in their normal or at rest position. As shown in Fig. 2, this means consists of a platel supporting a cushion, against which the type heads strike, and also supporting an upper protecting plate 32 which extends rearwardly over the type heads when said heads are in their normal at rest position against the cushion.

The platen carriage 16 is provided along its forward edge with a vertically arranged ratchet rack 33, said rack facing toward the When it is front of the machine. Mounted upon a rigid vsupport 34 is an escaplement dog 35.

This dog is provided with two pawls or de-V tents, which are adapted to engage the teeth of the rack, as clearly shown in Fig. 4. Connected to the escapement dog is an` operating arm 36 which is connected to the universal bar 37. The universal bar is pivoted in a standard 38 mounted on the base l of the machine, and extends forwardly and overliesthe members 3a of the key levers. As showninFig. l, the universal bar is segmental .in plan view, and is arranged to be v lifted by the depression of any one of the character keys, andby the space key, tobe hereinafter described. It is manifest that by lifting the forward portion of the universal bar the arm 36 is moved rearwardly, y

thereby operating the escapement dog in the usual manner to .permit the carriage to be moved one step for letter spacing. It will, of course, be understood that any suitable ,form ofescapement dog, or escapement device, to be operated by the universal bar, may be substituted for the escapement dog shown in the drawings, said `dog, being shown merelyby way of illustration.

The base plate l carries an upwardly extending cylindrical standard 39, whose verticalV axis is in vertical alinement with the center of the rotatable plate l1. y The central portion 5 of the carriage bed is formed with a dependingl tubular hub or socket 40, which is adapted to receive the cylindrical `standard onthe base plate, 'so that the bed plate maybe raised and lowered on the standard 39. Secured to the base plate are four upwardly extending sockets 4l; and depending from the central portion 5 of the bed plate are corresponding guide pins 42, `which fit and slide within said sockets. These pins and sockets maintain the carriage bed in its proper position on the base plate, while aty `the same time permitting vertical movement of said bed plate for the platen shift, as hereinafter described. Fivotally mounted at the sides ofthe keyboard are case shift levers 43- and 44, said leversbeing pivoted at dif-V ferent points, in order to give variable shift movement to the carriage bed. Each of these shift levers is provided at its rear end with conical ribbon guiding rollers .47, said rollersl being suitably mounted and one of them being provided with a ratchet 48. Over these rollers and through afribbon guide-49 I is passed-.an endless ribbon 50. The ribbon guide 49 maintains the ribbon at the printing point, and said guide is pivoted at51 to the upper end of a rigid bar 52, this latter to the universal bar and vibrated vertically by it is a pawl 53, which is adapted to engage the ratchet 48 on Vone of the ribbon guiding rollers 47. Below each of the ribbon guiding rollers isaninking pad 54 so that 4the ribbon will be freshly inked as. it passes betveen the guiding rollers and they inking pa s.

The. purpose of hinging the ribbon guide at 51 1s to permit it to be swung forwardly `out of the wayfof the platen when it is desired to move :the platen to its 'vertical folded position.

'The usual space key 55 isprovided, said space key being hinged in a manner similar to the hinges of the characterkeys; and the rear ends of the space key levers project under the universal bar so that the said bar may be operated by the space key.

It is manifest from the foregoing, that a typewriting machine constructed as herein described, may be folded intol a very small and compact package, suitable for transportation or for storage. The machine will not only be r-educed in length from front to rear,

c but will be materially reduced in width, and
